Abstract: This application discloses a communication method and a related apparatus. The communication method includes: A first core network element receives a first message from a second core network element, where the first message includes identification information of a first terminal and first identification information of a session, and the session indicated by the first identification information is used by a second terminal to transmit data for the first terminal; the first core network element obtains, based on the identification information of the first terminal, terminal context information corresponding to the session; and the first core network element sends a second message to the second core network element, where the second message includes the terminal context information corresponding to the session. This can directly control session permission of a terminal device, thereby improving accuracy of performing permission control on the terminal device.

Abstract: In a data transmission method, a first communication device obtains a data packet in a first direction, and obtains a data packet in a second direction. The two data packet correspond to a same service. If the first direction is an uplink direction, the second direction is a downlink direction; or if the first direction is a downlink direction, the second direction is an uplink direction. The first communication device determines a target transmission delay in the second direction based on a total transmission delay requirement and a time point at which the data packet in the first direction is sent. The first communication device sends the data packet in the second direction based on the target transmission delay in the second direction. The total transmission delay requirement is a sum of a transmission delay requirement in the first direction and a transmission delay requirement in the second direction.

Abstract: Embodiments of this application provide a data transmission method and a data transmission apparatus. The method includes: obtaining, by an access management network element, information about a connection status of a terminal device in a first network; and processing, by the access management network element, a data transmission procedure of the terminal device in a second network based on the information about the connection status of the terminal device in the first network. When the terminal device needs to transmit data through both the two networks, the method in the embodiments of this application can avoid a problem that the terminal device overuses a resource in either of the networks.
